Product FAQs
8 answersWhat panelboard systems is the HGA261002 compatible with?
As an I-Line style breaker, it is designed exclusively for Square D I-Line panelboards and switchboards. It features built-in plug-on jaws on the line side that clamp directly onto the internal I-Line bus, simplifying installation compared to standard unit-mount breakers.
Can the HGA261002 replace an older F-frame I-Line circuit breaker?
Yes. The Square D PowerPact H-frame series is the modern replacement for legacy F-frame I-Line breakers, such as the FA or FH series. It offers updated trip technology and higher interrupting capacities while maintaining compatibility with standard I-Line bus systems.
What are the required tightening torques for the standard lugs?
The factory-installed lugs require a 3/16 inch Allen wrench for termination. The required torque is 50 in-lbs for 14 to 10 AWG conductors, and 120 in-lbs for 8 to 3/0 AWG conductors. Proper torque is critical to prevent thermal issues at the connection.
Does this breaker require a separate mounting bracket to install?
No. As an I-Line style plug-in breaker, the line side connections are integrated directly into the housing. It snaps securely onto the panelboard bus without the need for additional mounting bases or hardware.
How do the trip settings operate on this specific model?
This circuit breaker utilizes a thermal-magnetic trip unit with a fixed thermal overload set at 100 amps. However, the magnetic instantaneous trip is adjustable, allowing panel builders to fine-tune the short-circuit pickup point to properly coordinate with downstream devices and avoid nuisance tripping from high inrush currents.
Can the HGA261002 be applied in direct current (DC) installations?
Yes. In addition to its AC ratings, this breaker is fully rated for DC networks up to 500 VDC. It provides a 20 kA interrupting capacity at both 250 VDC and 500 VDC, which is frequently required for solar PV systems, battery banks, or industrial DC control applications.
What does the letter G signify in the HGA261002 part number?
In the PowerPact nomenclature, the G indicates the specific interrupting capacity tier. A G-tier H-frame breaker delivers 65 kA at 240V AC, 35 kA at 480V AC, and 18 kA at 600V AC.
Can this circuit breaker be used in control panels destined for international export?
Yes, this model is designed for global compatibility. In addition to North American UL and CSA listings, it carries IEC approval and the CE mark, making it suitable for equipment exported to European and other international markets.
